Versatile Measurement Techniques to Validate Analytical Structural Mechanical Models
Abstract
The objective of this in-house work unit was to develop and improve structural measurement systems, facilities and techniques for the collection and analysis of static and dynamic loads data in an inexpensive, reliable and expeditious manner. The effort used state-of-the art instrumentation to collect and analyze data required to validly define the loads environment and provide the necessities for identification, prediction, prevention and control of vibration, static structural loads, dynamic flutter, acoustical loads and thermal stresses in areas of structural fatigue and damage. The Air Force needs common, versatile, advanced and inexpensive measurement systems to support numerous aerospace vehicles and aging aircraft. The approach includes environmental laboratory tests and flight tests of various types of flight data acquisition systems, sensors and components to ensure compliance with accuracy, life, flight worthiness, maintenance, size performance, weight, reliability and safety requirements of loads data collection systems. Measurement systems should maximize on-board memory, and minimize size, weight and power requirements. This effort illustrates AFRL measurement needs in the laboratory and in the field. Conduct in-house studies of new vibration and static testing and analysis techniques. Studies included purchasing or developing in-house software and conducting experimental programs utilizing Design of Experiments (DOE) to check current and proposed measurement techniques. This report contains papers that document the resultant projects conducted to validate new instrumentation.
